Elastomeric stopper sterilization system
Ensure sterilization and cleanliness of elastomeric vial stoppers with a system designed for seamless integration into your production line, optimizing processes from washing to unloading.

The Elastomeric Stopper Treatment Autoclave System by Fedegari automates the entire process of treating elastomeric vial stoppers, providing pharmaceutical manufacturers with a robust solution that combines washing, rinsing, siliconizing, sterilizing, drying, and automatic unloading. Employing a dual-purpose design, the system functions as both a stopper treatment unit and a steam sterilizer, ensuring versatile application within production lines. The process utilizes Thema4 control system for precise operation, while the rotating drum with magnetic coupling ensures unimpeded chamber space. Suitable for biopharmaceutical and pharmaceutical industries, it supports batch and continuous operations, handling both solid and powder product types. The system is constructed from AISI 316L stainless steel for maximum corrosion resistance and complies with GMP, FDA, and various international standards, reinforcing its suitability for sterile environments. Its ease of integration and adaptability to customer-specific needs make it an invaluable asset in maintaining aseptic conditions and optimizing stopper processing workflows.
